Application filed July 17, 1925. Serial No. 44,387.

y invention relates to improvements in electrically controlled valves, and it consists in the combinations, constructions -and.ar-

' rangements herein described and claimed.

A further object of my invention is to provide an electrically controlled valve which is simple in construction, durable and thoroughly practical for the purpose in tended.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be lparticw larl pointed out in the appended c aim.

y invention is illustrated inthe accompanying drawing forming part of this application, in which Figure 1 is a front elevation of an embodiment of my invention, a; part thereof ,mina-l 9 of the motor 1 be'dg in section with the casing removed, an

Figure 2 is a top plan view of the device illlustrated in F lgure 1 with the casing in p ace.

- In carrying out my invention I make use of an electric motor 1 which is connected to an electric power source 2 through lead wires 3. A manually actuated switch 4 is connected in serieswith one of thelead wires 3 shown in Fi 1.

My improved electrically controlled valve consists in a pair of solenoid coils connected in series and disposed concentric with a tubular member 6 of The coils 5 have their bymeane of conductors disposed adjacent to wire of opposite poterminals connected the switch 4 and to the larity extending from the power source 2.

A laminated core is disposed about the solenoid coils 5" and secured to the tubular I member 6 by encompassing the tubular member 6 with certain of the leaves of the core.

ed within the tubu end of the tubular member 6 is closed by 70 through of the valve member'24, whereby gas may 100 insulating material.

7 and 8 to the ter- The core 10 is'bound together and to a casmg consisting of two parts 11- and 12 respectively by thQ'PIOVlSIOII of screws 13 having nuts14'projected' through the'parts of 60 the casing 11 and 12 and through the core A stationary central laminated core piece 15 is disposed within the tubular member 6 at the upper end thereof and is secured a bolt 16 projected diametrically 05 thereto b through t core.

A solenoid coree tubular member and through the iece 17 is slidabl' mountar member 6. Th

means of a threaded metal M 18 having a threaded aperture, 19 which a gas pipe 20 is threaded. The gas pipe 20 is connected with a source of gas sugply, 7 v I he lower end of the tubular member fi has a metal chamber 21 secured thereto and communicating with the interior-ofv the tubular member. A member 21 having a valve I the interior of 80 seat 22 communicates with the chamber 21 and is securedthereto by means of threads 23 on the exterior wall of the member 21" and on the interior walls of the end opening provided through the bottom wall of th members 21 and 21. The valve member 24 is secured by means of a rod 25 to the solenoid core 17, so that when the solenoid-core 17 is drawn upwardly, the solenoid coils 25, lifted from its seat 22.

The valve'member 24 has a substantially tubular ort" )1]. at the lower end thereof communicating member 21' beneath the valve as shown in dotted lines at. 26.

Openings 27 are provided transversely the side walls of the lower portion.

the valve 24 will be pass from the chamber 21 through the openings 27 and by way of the tubular portion 26 to the interior of the member 21. 1 The lower portion of the member 21 is connected by means ofa burner 29. At 30 I have illustrated paper disposed over the burner 29 as when the paper is moved over the burner during the drym process. 'It should be remembered that t a paper 3 0" is in motion during: all 110 times when the motor lis' in operation. The solenoid coils andthe motor are operated e upper theret rough into e chamber 21. A valve 88 member 24 is disposed within-the registering as by energiiation of 90 'with the interior of the ipe 28 to a gas the burner 29 w1 be in eration.- A connection 31 leads to a pilot light 32.

I openin 'From the foregoing description of the various parts .of the device the operation thereof may be readily. understood. When the motor 1 which operates the press is placed inv operationby closing the switch 4c,-

current will also be conducted to the solenoid coils 5 which will become energized to cause the solenoid core 17 to rise, thus the valve 24. Gas may then pass throug the tubular member 6, through the chamber 21 and to the burner 29 through the pipe 28 so as to dry the paper 30.

I claim An electrically controlled valve comprisa valve seat, a gas-conveying conduit connect-ing said chamber with said burner, a

valve, a cylindrical guide integral with said valve and having openings therein, said. guide slidably disposed in said chamber, a tubular member connected to said valve chamber, a solenoid core piece slidably mounted within the tubular member and being operatively connected to said valve, a solenoid coil disposed about said tubular member, a gas pipe for connecting gas to said tubular member, a pilot light disposed adjacent to said gas burner, and a by-pass connecting said pilot light with said valve chamber at a point above the valve.
